Dear Robert,
I have the same problem, which is even worse from the fact, that the
cron is hanging up after this warning. This is exactly that what I'm
getting in the log file:

Title:
GD Image not being created during cron run
Status in Mahara ePortfolio:
New
Bug description:
I get the following warnings when cron job 'cron_site_data_daily' runs
- I'm not sure if it's specific to my data / machine / php version
(which is 5.4) but I thought I'd mention them here in case others were
having the same problems.
The failure means that the statistic graphics are not generated.
